Grooving machine for underground grouting continuous wall construction and construction method

Abstract

The invention relates to the field of building construction, in particular to a grooving machine for underground grouting continuous wall construction and a construction method. The grooving machine comprises a machine table and a grooving device, wherein the grooving device is slidably connected with a base table, the grooving device comprises a mounting frame, drill rods and drill bits, the drill rods are rotatably connected with the mounting frame, the drill bits are fixedly connected with the drill rods, two rows of drill rods are arranged in parallel, and drill holes drilled by the two rows of drill bits are arranged in a tangent mode. In the invention, the two grooving processes are reduced to one time, meanwhile, the one-time standing cement slurry solidification process is also reduced, then the construction period of the double-width continuous wall is greatly shortened, and the purpose of improving the construction efficiency of the double-width continuous wall is achieved.

Description

Technical field[0001]The present application relates to the field of building construction, in particular, involving a slotting machine and construction method for underground grouting continuous wall construction.Background technique[0002]At present, the underground continuous wall is a continuous underground wall with waterproof, retaining and load-bearing function, which is widely used in the basement, parking lot, high-rise building of buildings, and underground. When the trench of the continuous wall is excavated, the wall needs to be achieved by means of mud.[0003]Selling machines are often used when excavating underground continuous walls.figure 1 The slotting machine includes a machine 1, a guide 2, a lifting device 3, and a slotting device 4, and the machine 1 is disposed on the ground of the construction site, the guide rod 2 is vertically disposed, the guide rod 2 is fixed to the machine 1 fixed In connection, the lifting device 3 is located at the top of the guide bar 2,...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: when using a slotting machine to dig a trench whose width is twice the standard width, it is necessary to dig the trench with the standard width twice before and after, and the front and rear sides There is a time waiting for the concrete to solidify between excavation work, and the construction period is long, resulting in low construction efficiency of the continuous wall
